Do you trust in regard to the child of humanity?
Jhn 9:35 Dost thou believe on the Son of God?
Interesting and Hidden Aspects:
The main difference here between the KJV and the alternative comes from the source material. The Greek source of the KJV has this verse reference the "child of divinity" while today's more complete sources have it as "the child of humanity.
This verse in its KJV and the Greek sets up a basic contraction that we can see through much of the NT. Do we trust in Christ as the flowering of humanity or as the offspring of the divine? Christ himself, of course, is both at once, but when he asks to be trusted it is as the flowering of humanity, the perfection of what we can be, rather than as the Other, the divine to which we can never aspire.
